Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
Referring to fig. 1-7, a portable adjustable pneumatic hydraulic jack is provided in a first embodiment of the present utility model, and the portable adjustable pneumatic hydraulic jack comprises a base 110, wherein a connecting shaft 111 is rotatably connected to a left side wall of the base 110, a connecting piece 112 is fixedly arranged on the connecting shaft 111, a pull rod 113 is fixedly arranged on an upper end of the connecting piece 112, and a grip 115 is fixedly connected to an upper end of the pull rod 113;
the upper end of the pull rod 113 is provided with a pressure regulating valve 116, and the pull rod 113 below the pressure regulating valve 116 is provided with a pressure stabilizer 114;
wheels 123 with symmetrical front and rear positions are arranged on the right side wall of the base 110, and universal wheels 122 with symmetrical front and rear positions are arranged on the left side wall of the base 110;
